The goal of this spec is to outline how the header of the static server-delivered page should be crafted in order to display per-social network custom format of the included share link snippet.

These networks display shared link as a snippet attached to custom share post message (which the user types in when sharing).

In order to deliver a custom snippet for each social network, a different static link has to be provided for each one, as there is no way to make differing headers for all the networks in one HTML page.

Therefore, I strongly suggest to have a GET parameter as follows:

http://tellmaps.com/?subject=WDAIND01&sharing=facebook
http://tellmaps.com/?subject=WDAIND01&sharing=linkedin
http://tellmaps.com/?subject=WDAIND01&sharing=googleplus

I don't recommend to share the urls in new URL format. A fallback which the server will process and redirect to new URL format is the most reliable solution, as the new URL format may be google-crawlable, but support in share snippet may vary.*

Actually, there is no way to display a snippet for twitter. Therefore, we will leave the “tweet” feature the same as in current tellmaps.
